### 7.2.3 INTERMEDIATE SYSTEM TO INTERMEDIATE SYSTEM - DUAL IS-IS

The American National Standards Institute (ANSI) X3S3.3 committee has defined an intra-domain routing protocol. This protocol is titled Intermediate System to Intermediate System Routeing Exchange Protocol.

Its application to an IP network has been defined in [ROUTE:2], and is referred to as Dual IS-IS (or sometimes as Integrated IS-IS). IS-IS is based on a link-state (SPF) routing algorithm and shares all the advantages for this class of protocols.
